How can I get the markers in the file (aka region view) without having to rerender the entire file? It seems to be the associate files that the markers are defined in, is there some way to create this sfk (or whatever) file?
You could render a stereo DVD .ac3 file. This is quite fast, usually better than 10x realtime. That's how i add markers to a DVDA project if i forgot to include them in the MPEG file. I'm not sure if Vegas will do anything with it though.
